Preparation

Preheat oven to 350°F. Lightly grease 13X9-inch baking dish. Heat oil in large skillet over medium heat. Add onion and bacon; cook until onion is tender. Add beef; cook and stir about 5 minutes or until beef is no longer pink. Stir in tomatoes, cheese, salt and black pepper. Spoon mixture into cooked shells; place in prepared baking dish.

Cut carrots into very thin strips. Cut small slit in each olive; poke one end of thin carrot strip into each olive for "eye." Cut red bell pepper into fang shapes. Slice pickle lengthwise to make tongue shape. Cut cheese slice into zig-zag pattern for teeth.
